Abstract The objective of this research is to explore the feasibility of a chipless RFID tag that stores a data signature in the form of complex frequency plane singularities. To this end an existing chipless RFID tag, the notched elliptical dipole tag, was analyzed first with simulations and then measurements. A pole signature was extracted from simulations, and individual poles were determined via experimentation to be attributable to specific controllable features of the tag. The poles were shown to be independent of both excitation and observation. A prototype tag was measured, and the pole signature was retrieved from the scattered fields. The tag was successfully read for different orientations showing that embedded singularities can be used as a means for encoding and retrieving data.
